From Wyverns to Whispers: The Story Behind The Nanny’s Secret by J. Cronshaw

Full-time author J. Cronshaw shares how his first domestic thriller, The Nanny’s Secret, began as a creative break after writing his epic fantasy series The Ravenglass Chronicles. Discover how he moved from wyverns to psychological suspense, creating a new pen name and a new direction for his writing career.

The Nanny’s Secret was the first domestic thriller I ever wrote—but it wasn’t my first novel.

I’ve been a full-time author since 2018, publishing fantasy and speculative fiction since 2016. Most readers know me for The Ravenglass Chronicles, a sprawling epic fantasy series full of wyverns, assassins, and strange magic.

Over several years, I built an entire universe of interconnected stories—epics, novellas, side tales, and serials—all tied to my fictional Ravenglass Universe.

And in 2022, I decided to write something entirely different—a palate cleanser.

At the time, I was reading a lot of psychological thrillers. They’d become my comfort genre when I wasn’t deep in fantasy worldbuilding. I loved the tension, the secrets, the slow unravelling of trust between ordinary people. It’s a form of storytelling that hits close to home—less about saving kingdoms and more about saving face, marriage, or sanity.

That was how The Nanny’s Secret began.

I didn’t plan for it to go anywhere. It was supposed to be a one-off project, something fun to write before diving back into fantasy. I even told myself that no one would ever see it. After all, it didn’t fit my established author brand. I’d spent years building an audience for fantasy, and the idea of confusing readers—or having to start from scratch with a new pen name—didn’t appeal at all.

But something about writing The Nanny’s Secret felt different.

It was grounded. Real. Intimate. The story came easily, rooted in the kind of small-town settings I knew so well. It pulled from my experiences as a court reporter, from the cases and human stories I’d seen up close—people under pressure, lies unravelling, families falling apart behind closed doors. The world didn’t need dragons or magic to feel dangerous; the tension came from truth.

When I finished it, I thought that would be the end of it. But then I had another idea. And another. Before long, I’d written a second domestic thriller, then a third. Now, a few years later, I’ve written eight—and I’m currently working on my ninth.

At some point, I shared a few of them with a friend of mine who writes thrillers. He told me they were good—publishable, in fact—and that I needed to stop hiding them away. I explained that I didn’t want to confuse my fantasy readers, and that I didn’t want the hassle of building another brand from scratch.

His response was simple. “Drop your first name,” he said. “Make it J. Cronshaw. It’s still you, just different shelves.”

That small change opened everything up.

So here we are. The Nanny’s Secret is now out in the world under my new pen name, J. Cronshaw. It’s been both exciting and humbling to begin again from the ground up—building a new website, setting up social media accounts, creating a fresh newsletter, and reaching a completely new readership.

I was hesitant at first. It felt strange to be “new” again after years of being an established author. But it’s also been freeing.

These thrillers have given me a creative outlet that feels personal and immediate. They let me write about real places near where I live—Morecambe, Heysham, Lancaster—and draw from my own surroundings. I walk those streets, hear those accents, see the same coastal skies my characters do. Every story feels grounded in reality, not in distant kingdoms or imagined empires.

It’s a change of pace from wyverns and princesses, and I love it.

There’s something invigorating about rediscovering the thrill of being a beginner, but with the benefit of experience. I know the pitfalls to avoid this time. I know how to pace a story, how to connect with readers, and how to sustain a long-term creative life. That mix of newness and confidence has made this transition incredibly rewarding.

I can’t wait to share more of these thrillers with you. They’re stories I care deeply about—tales of secrets, lies, and the fragile edges of everyday life. And if the ideas keep coming at the rate they are now, I’ll be writing them for many years to come.

If you’d like to follow along with what I’m working on, you can listen to my Author Diary podcast, available on Spotify or any podcast app. I’ve been recording a weekly episode since 2017, talking about my writing, reading, and creative life—and I haven’t missed a single week.

It’s funny. When I started The Nanny’s Secret, I thought it was a one-off experiment. Now it feels like the start of something much bigger.

And I couldn’t be happier about it.

What Makes a Thriller a Domestic Thriller?

What makes a thriller a domestic thriller? Discover the key traits of this addictive genre—from family secrets and betrayal to gaslighting, obsession, and the danger inside your own home.

Domestic thrillers are some of the most addictive books on the market today.

They keep readers turning the pages late into the night, not with car chases or international conspiracies, but with something far more unsettling—the idea that danger lives right inside our homes.

So what makes a thriller a domestic thriller?

Let’s break down the essential traits of this hugely popular genre.


The Setting: Home, Family, and the Familiar

Domestic thrillers thrive in ordinary places.

Instead of foreign battlefields or secret government bunkers, the drama unfolds in suburban houses, quiet neighbourhoods, and family kitchens.

The terror comes from the fact that the setting is familiar. Readers recognise these spaces. They live in them.

The question becomes: what if the person you share your home with can’t be trusted?


The Characters: People You Know

Unlike espionage thrillers or police procedurals, domestic thrillers rarely feature elite agents or hardened detectives.

The characters are ordinary people—mothers, fathers, neighbours, partners.

That’s what makes the danger so sharp.

It’s not about battling strangers; it’s about questioning the people you love and rely on most.

The husband who has secrets. The lodger who wants more than a room. The friend who isn’t who she says she is.


The Themes: Secrets, Lies, and Betrayal

At the heart of every domestic thriller are the themes of secrecy and betrayal.

These stories expose the cracks beneath perfect-looking lives.

Common themes include:

  • Family secrets that refuse to stay buried.
  • Infidelity and deception within marriages.
  • Gaslighting and manipulation, leaving characters unsure of their own sanity.
  • Obsession and control, often from someone close to home.

The tension builds as characters uncover the truth—and the cost of that truth.


The Villain: Close to Home

In domestic thrillers, the antagonist isn’t a terrorist or serial killer lurking in the shadows.

More often, it’s someone inside the circle of trust: a partner, a family member, a new friend, or a neighbour.

This closeness is what makes the genre so chilling.

The line between safety and danger blurs when the threat shares your dinner table or holds the spare key to your house.


The Reading Experience: Unsettling and Addictive

Domestic thrillers are addictive because they feel possible.

Readers know they won’t wake up as a secret agent, but they might discover their spouse isn’t who they thought. They might trust the wrong neighbour. They might invite danger in without realising it.

That plausibility is what keeps us turning the pages, whispering: What would I do in that situation?


Popular Domestic Thriller Authors

If you’re curious about domestic thrillers, some of the most successful names in the genre include:

  • Lisa Jewell (The Family Upstairs, None of This Is True)
  • Shari Lapena (The Couple Next Door, Not a Happy Family)
  • B.A. Paris (Behind Closed Doors, The Therapist)
  • Adele Parks (I Invited Her In, Both of You)

These authors specialise in turning safe, suburban lives into nightmares of secrecy and suspicion.


Why I Write Domestic Thrillers

As a former journalist reporting from Crown Courts across Yorkshire, I saw countless cases where ordinary people’s lives unravelled because of hidden debts, family disputes, or secrets kept too long.

Those experiences inspired me to write my own domestic thrillers, like The Lodger—a story about a widowed mother who lets a stranger into her home, only to realise this young woman wants far more than just a place to stay.

It’s the same fascination that fuels the genre as a whole: ordinary people, extraordinary danger, and the terrifying possibility that it could happen to any of us.


Final Thoughts

So, what makes a thriller a domestic thriller?

It’s the shift from external threats to internal ones. The drama happens in kitchens and living rooms, with characters who feel uncomfortably familiar, facing betrayals that hit close to home.

If you enjoy twisty, page-turning stories about secrets and lies in ordinary families, domestic thrillers are the perfect genre for you.
